Hue Job Browser is not working

[#1]

We upgraded our cluster from 5.4 to 5.8.2 version, and after the upgrade we have some problem with Job Browser in the HUE.

The problem is that I can see the running jobs in the YARN resource manager UI, but I don't know why I can't see running jobs in the Hue.

I have googled a lot, but couldn't find anything related to it.

The only thing that I have found is the yarn resource manager format state store.

So I have executed following:

#1
stop ressource manager (yarn)

#2
yarn resourcemanager -format-state-store

#3
start ressourcemanager (yarn)

After this the problem has been solved.

But after some time (around 3-4 days) the issue appeared again.

I could reproduce this problem in two different environments.

Do you have some ideas ? 

Thanks in advance!

I some how make it working by manually tweaking jobbrowser/api.py.  Please check it in https://github.com/cloudera/hue/issues/451

Rolling restart of Resource Manager fixed issue for me

Setting up the following env variables worked for me:

CORE-SITE.XML_hadoop.proxyuser.hue.groups=*
CORE-SITE.XML_hadoop.proxyuser.hue.hosts=*

These correspond to settings in core-site.xml
